ARTHUR L. HOOVER, or AVERY, 01nd FOR P OTATO-DlG-GIEBS.

Patented Sept. 18,

To (all 1117mm it may concern:

Be it knownthatl, ARTHUR L. HOOVER, a} citizen of the United- States, residing .at Avery, in the county of Erieand-State of Ohio, have invented anew and useful Colter. Attachment for Po tato Diggers, of which the: following is a specification. i

This invention has relation to colter attachments for potato-diggers; and it consists in the novel construction and arrangement of its parts, as hereinafter shown and described.

The object of the invention is to provide 'anattachment for implements of the character specified, said attachment carrying colter-wheels which are adapted to cut the ground in advance of the potato-plow and at each side thereof, said wheels being so mounted and carried by a bell-crank lever that they may be thrown out of the ground, and at the same time the potato-plow will be elevated above the ground. When the above operation is reversed and the colter-wheels brought in contact with the ground, the potato-plow is also lowered into the soil.

In the accompanying drawings, Figure 1 is a side elevation, partly in section, of a potato-digger, showing the colter-wheels and potato-plow operating in the ground. Fig. 2 is a side elevation of a potato-digger, showing the colter-wheels and the potato-plow elevated above the ground. Fig. 3 is a pers ective view of the colter-wheels, showing t e bell-crank lever to which they are attached. Fig. 4 is a top plan view of the bellcrank lever and its-attachments.

The potato-digger l is provided with the forwardly-extending frame 2. The castings 3 3 are attached to the forward ends of the frame 2, and between the said castings the bell-crank lever 4 is journaled. The castings 5 5 are attached to the bell-crank lever 4 on the outer sides of the castin 3. The pins 6 are held by means of the col ars 7 and 8 in the forward ends of the castings 5, the said collars 7 and 8 being held in position upon their respective pins 6 by means of setscrews. The arms 9 are swiveled to the lower ends of the pins 6, and between said arms the colter-wheels 10are journaled. The bowed intermediate portion 11 of the bellcrank lever 4 extends to the front, and when the colter-wheels 10 are in contact with the ground the said intermediate portion 11 of the said bell-crank lever inclines upwardlytoward its outer end. When the colterwheels 10 are elevated above the ground, the

I said intermediate pontion 11 of the bell-crank llever 4 extends downwardly at its outer end.

The said portion 11" of the lever 4 passes through the elongated o ening of an eye 12, and thesaid eye-12 isfa apted to be coupled lto; the. tongueebeai'ing' V truck 1 3 The lever '14. isf'atta'ched at its forward end to the eye 12 and at its rear end is pivoted to the working end of the lever 15 or an extension thereof, said lever 15 being suitably fulcrumed upon the frame of the potato-digger 1 and having a spring-actuated pawl adapted to engage the rack-se ment 16. It will thus be seen that when the free end of the end of said lever is elevated. The lever 14 is oscillated on its fulcrum and through the eye 12 causes the intermediate portion. 11 of the bell-crank lever 4 to assume a downward incline. As the said eye 12 restsupon the tongue-bearin truck 13 and as the upper surface of sai relative hei ht above the surface of the ground, the orward end of the framework of the potato-digger 1 is elevated and the potato-plow is ralsed above the surface of the ground- At the same time the colter-wheels are also raised above the surface of the ground. By reversing the operation above described the colter-wheels 10 and the potato-plow are caused to engage the ground substantially at the same time. The lever 14 may serve as a support for a tool-box-17, as indicated in the drawings.

\Vhat I claim as new is 1. In combination with a plow-bearing implement and a tongue-bearing truck, an implement and truck-connecting means pivoted for vertical swing u on the implement, and a colter pivoted for orizontal swing on said means.

2. In combination with a plow-bearing imtruck is always at the same plement and a tongue-bearing truck, an implement and truck-connecting means pivoted for vertical swing upon the the implement, a colter pivoted for orizontal swing on said means, and a lever mechanism for operating said truck-connecting means.

3. In combination with a plow-bearing implement and a tongue-bearing truck, a bellcrank lever fulcrumed upon the implement and connected to the truck, colters supported at the ends of said lever, and mechanism for operating said lever.

4. In combination with a plow-bearing im plement and a tongue-bearing truck, a bellanwmian ngn 7 O lever-1 5 is brought to the rear that theworking crank lever fulcrumed to the implement and connected to said truck, arms swiveled at the ends of said lever, colter-wheels journaled to said arms, and a lever mechanism for operating the bell-crank lever.

5. In combination with a plow-bearin implement and a tongue-bearing truck, a ellcrank lever fulcrumed to the implement and connected to said truck, forwardly-extending castings secured to said bell-crank lever, pins supported by said castings, arms swiveled to said pins, colter-wheels journaled in said arms, and a lever mechanism operatively connected with said bell-crank lever.

6. In combination with a plow-bearing im- ARTHUR L. HOOVER.
